SOME of the cases undergoing the cold-case-review process include high-profile murders that shocked the nation, writes Tom Brady.

One of the unit's earliest cases was the fatal stabbing of Raonaid Murray (17), whose body was found by her elder sister on a road close to her home at Silchester Crescent, Glenageary, Co Dublin, in the early hours of Saturday, September 4, 1999.

Several people have been questioned about her murder but there have been no charges. The cold case team is hoping to complete the full review of the investigation shortly.

Another perplexing case for the team is the death of Grace Livingstone, a 56-year-old mother of two, who was found face down on her bed in her home at The Moorings, Malahide, Co Dublin, on December 7, 1992.
